Effects of the Hypnotic Agent on Primary Graft Dysfunction After Liver Transplantation.

BACKGROUND: Morbidity and mortality rates in orthotopic liver transplantation have decreased in the past few years. Risk factors related to severe postoperative complications, such as primary graft dysfunction, still need to be analyzed. We evaluated the influence of the hypnotic agent used during anesthesia on primary graft dysfunction.

METHODS: We performed a retrospective analysis of 419 consecutive patients who received a liver transplant between 2005 and 2013 in a single center. We analyzed the incidence of primary graft dysfunction (defined as alanine aminotransferase or aspartate aminotransferase levels higher than 1500 IU/L on the first 3 days after surgery) and if the hypnotic agent was associated with this event.

RESULTS: The incidence of primary graft dysfunction was 42.2% (114 patients), similar in both groups (propofol group, 89 patients, 43.2% and sevoflurane group, 25 patients, 39.1%). In the multivariate analysis, we did not find any relationship between the hypnotic agent (propofol or sevoflurane) and early graft dysfunction.

CONCLUSIONS: In our patients, we found no differences in the incidence of liver graft dysfunction according to the hypnotic used during transplantation. We can suggest that both drugs (sevoflurane and propofol) are equally safe in orthotopic liver transplantation.
